BACKGROUND: Osmotic Fragility Test (OFT) is widely considered as a sensitive indicator of red blood cells' sensitivity to the hypotonic solution. It is often used as a screening test for the diagnosis of hereditary spherocytosis (HS). Nowadays, the osmotic fragility test based on flow cytometric analysis (FCM OF) is widely used in laboratory practice. The purpose of this study was to optimize the assay sensitivity and to validate its clinical application in the diagnostic screening of childhood anemias...

OBJECTIVES: The Toba/Qom of Namqom are an indigenous community native to the Gran Chaco region of northern Argentina. Historically seminomadic foragers, the diet of peri-urban community members has rapidly changed from high-protein, high-fiber to hypercaloric, processed. This study aims to understand the impact of this nutritional transition on aspects of women's health by exploring the relationship between prevalence of anemia and current diet composition, place of birth, and reproductive history...

High hypoxic, glycolytic and acidosis metabolisms characterize cervical cancer tumors and have been described to be involved in chemoradioresistance mechanisms. Based on these observations, the present study assessed four selected novel biomarkers on the prognosis of locally advanced cervical carcinoma. A total of 66 patients with stage IIB/IIIB cervical cancer were retrospectively included. The protein expression levels of glucose transporter 1 (GLUT1), carbonic anhydrase 9 (CAIX) and hexokinase 1 (HKII) were investigated by immunohistochemistry on tumor biopsies, hemoglobin was measured and the disease outcome was monitored...

BACKGROUND: India's high prevalence of iron-deficiency anemia has largely been attributed to the local diet consisting of nonheme iron, which has lower absorption than that of heme iron. OBJECTIVE: We assessed the efficacy of the consumption of iron-supplement bars in raising hemoglobin concentrations and hematocrit percentages in anemic (hemoglobin concentration <12 g/dL) Indian women of reproductive age. DESIGN: The Let's be Well Red study was a 90-d, pair-matched, cluster-randomized controlled trial...

Fetal insulin secretion is inhibited by acute hypoxemia. The relationship between prolonged hypoxemia and insulin secretion, however, is less well defined. To test the hypothesis that prolonged fetal hypoxemia impairs insulin secretion, studies were performed in sheep fetuses that were bled to anemic conditions for 9 ± 0 days (anemic, n=19) and compared to control fetuses (n=15). Arterial hematocrit and oxygen content were 34% and 52% lower, respectively, in anemic vs. control fetuses (P<0.0001). Plasma glucose concentrations were 21% higher in the anemic group (P<0...

BACKGROUND: Prior conclusions that autologous neonatal red blood cells (RBC) have substantially shorter lifespans than allogeneic adult RBCs were not based on direct comparison of autologous neonatal vs. allogeneic adult RBCs performed concurrently in the same infant. Biotin labeling of autologous neonatal RBCs and allogeneic adult donor RBCs permits concurrent direct comparison of autologous vs. allogeneic RBC lifespan. METHODS: RBCs from 15 allogeneic adult donors and from 15 very low birth weight (VLBW) neonates were labeled at separate biotin densities and transfused simultaneously into the 15 neonates...

BACKGROUND: Hypogonadism is common in patients with renal dysfunction and does not always correct following transplantation. Recent studies show increased mortality for dialysis and transplant patients with low testosterone (T). These patients are often not treated due to concerns over efficacy and complications (both real and imagined). There is surprisingly scant literature supporting the use of T therapy in these patients. We wished to examine the results of T therapy in our patients with renal failure or following transplant...

The ingestion of extraneous substances is quite common in clinical practice; it usually befalls in the pediatric age, mostly between 6 months and 6 years. In most cases, complications do not emerge, and the prognosis is considered favorable. However, when a case of battery ingestion occurs, serious adverse events may develop. The ingestion of these components is a potential life-threatening event for children.In this article, we report the case of an 18-month-old child who died from hemorrhagic shock due to an aortoesophageal fistula caused by a 20 mm lithium button battery lodged in the esophagus...

Photo-thermal angular light scattering (PT-AS) is a novel optical method for measuring the hemoglobin concentration ([Hb]) of blood samples. On the basis of the intrinsic photothermal response of hemoglobin molecules, the sensor enables high-sensitivity, chemical-free measurement of [Hb]. [Hb] detection capability with a limit of 0.12 g/dl over the range of 0.35 - 17.9 g/dl has been demonstrated previously. The method can be readily implemented using inexpensive consumer electronic devices such as a laser pointer and a webcam...

BACKGROUND: Chronic kidney disease (CKD) affects 10-15% of adult population worldwide. Incident patients on hemodialysis, mainly those on urgent-start dialysis at the emergency room, have a high mortality risk, which may reflect the absence of nephrology care. A lack of data exists regarding the influence of baseline factors on the mortality of these patients. The aim of this study was to evaluate the clinical and laboratory characteristics of this population and identify risk factors that contribute to their mortality...

BACKGROUND: Red blood cell transfusion related to select surgical procedures accounts for approximately 2.8 million transfusions in the United States yearly and occurs commonly after hip fracture surgeries. Randomized controlled trials have demonstrated lack of clinical benefit with higher versus lower transfusion thresholds in postoperative hip fracture repair patients with cardiac disease or risk factors for cardiac disease. The economic implications of a higher versus lower hemoglobin (Hb) threshold have not yet been investigated...

Nicaragua's Bosawás Biosphere Reserve is a vast forested area inhabited largely by indigenous Mayangna and Miskitu people. Most Bosawás residents rely on subsistence hunting and swidden agriculture, and hunting dogs are important for finding and securing wild game. We investigated the health of hunting dogs in three communities differing in location, size, and economy. Dogs in all communities were nutritionally compromised and experienced a heavy burden of disease. Seroprevalence of canine distemper, canine parvovirus, Rickettsia rickettsii, and Leptospira spp...

Mutations in hemoglobin can cause a wide range of phenotypic outcomes, including anemia due to protein instability and red cell lysis. Uncovering the biochemical basis for these phenotypes can provide new insights into hemoglobin structure and function as well as identify new therapeutic opportunities. We report here a new hemoglobin α chain variant in a female patient with mild anemia, whose father also carries the trait and is from the Turkish city of Kirklareli. Both the patient and her father had a His58(E7)→Leu mutation in α1...
